Being as it is, a book for more experienced users, Power Tools jumps straight into the good stuff. After a brief introduction on the book's intended audience and purpose, Chapter 2 deals with mastering loop-based composition techniques. Included are methods for slicing, dicing, combining, and otherwise modifying loops to create great sounding effects. Many of these effects are frequently heard in pop, dance, and hip hop music, and you'll be well served to add them to your arsenal.
Chapters 3 and 4 cover audio and MIDI techniques. Many of these techniques get their shine from author Francis Preve's aforementioned experience in music engineering and production. If you are not an experienced music producer or engineer, then you'll find the tips in these sections to be less-than-obvious, but incredibly helpful. As with most of the lessons in the book, the tutorials in these sections result in musical parts that sound highly distinctive and unique, and will allow you to strectch the standard GarageBand loop sets to their maximum potential. If you've got an add-on loop set or are working with your own music inputs, you'll go even further. One example of a great tip from the book is that certain software instruments respond differently to the MIDI sends from a modulation wheel/controller. The books tells you which instruments to look for, and what the modulation does for those instruments.
Chapters 5 and 6 are centered on GarageBand's software instruments and effects. Many who have dug into the settings and preferences in Apple's built-in GarageBand software instruments and effects have noticed that there is a huge amount of capability and configurability to the program. Of course, understanding these powerful features is something that is not so obvious and which most GarageBand users are likely struggle with. Indeed -- most of the effects and their settings come from Apple's professional audio application, Logic Pro.
The Power Tools section on software instruments explains many of the nebulous concepts behind old-fashioned synthesizers that are ubiquitous in much electronic music today. In addition, settings for more traditional instruments are explored, however the emphasis is on digital and analog synths. If you ever hoped to understand things like cutoff, attack, decay, envelope, and other characteristics of the GarageBand software instruments, and how they effect the sound you get from changing each of these settings, Power Tools is just for you. Special time is spent on the following instruments: Analog Basic, Analog Mono, Analog Pad, Analog Swirl, Analog Sync, Digital Basic, Digital Mono, Digital Stepper, Electric Piano, and Tonewheel Organ. Likewise, many of the effects in GarageBand are walked through, with Power Tools describing what various sliders will change the in the effected sound, and when such changes might be beneficial.
The final production-oriented chapter of Power Tools gives you a number of great tips for creating your mix down. This is where the author's experience in this area really shows and you are sure to benefit from the ideas contained in the chapter. The final chapter covers various add-on components that work with GarageBand. As a wonderful bonus to the book, a CD-ROM containing 150 Megabytes demo, shareware, or freeware tools is included, so you can get straight to pushing GarageBand past its as-shipped limits.
